The charger said they were at 49% charged. They did take a charge and started the truck easily several times since. However, they are four year-old WalMart batteries, so I'm thinking I should replace them. You've praised AGM batteries in the past. Sears has these: https://www.sears.com/diehard-advanced-gold-agm-battery-group-size-48/p-02850748000P?sellerId=SEARS&prdNo=2&blockNo=2&bloc kType=G2 The guy will sell them to me for $176.99 plus $40 installation (which I could do myself if I didn't want to help Trump's employment numbers). And, being ex-military, he'll give me another 10% off. So I could get them for about $160 each. Thoughts? I could get the non-AGM's for about $40 less
each.
Are AGM's worth the extra bucks? === For what it's worth, I've replaced all of the lead-acid 8D starting batteries on our boat with pairs of AGM group 31M batts in parallel. The 31Ms are half the weight and much easier to handle. They also have more cold cranking amps and a higher charge acceptance rate. Last but not least they are lasting twice as long as the 8Ds. --- This email has been checked for viruses by AVG. https://www.avg.com Costco has AGMs and I think installation is free. One of my near neighbors with a pick-me-up truck similar to mine went with an Odyssey AGM, group or size 34 something. He said it had more cold cranking amps than the others he considered. I happened to see him installing it last year, and just for fun I hefted it up off his garage floor. Sucker must weigh 50 pounds.

Surprise. Batteries are pretty heavy. I hope you didn't hurt yourself.

A 50 pound battery is a lightweight by my standards. My old 8D boat
batteries were about 170 pounds each and had to be hoisted over large
engines. The new group 31 AGMs are about 70 lbs and considerably
easier to manage.


Well, my recollection was that the Group 34 AGM seemed to weigh about
50% more than the last "old style" Group 34 battery I replaced in an SUV.

Sounds like you got ripped off.
